keratin is a fork of clipmenu, a simple clipboard manager using dmenu and xsel/xclip.
To use it, start the keratin-d daemon by calling keratin -d and then call keratin to launch
dmenu. Upon choosing an entry, it is copied to the clipboard. Entries can also be deleted via the
command keratin -D.
Some of the flags for customizing dmenu (-fn, -nb, -nf, -sb, -sf) are available to use with keratin.
You invoke them in the same way you would with dmenu (e.g. keratin -nb '#000000' -nf '#FFFFFF').
